[CLIENT] Pop-up blocks champ select screen

In the new client, as I was in queue I was looking at a friend's match history because he was telling me about how op Yasuo was and that this one game was proof, we found a match so I accepted, only to find that I was unable to chat or select a champion, causing a dodge. I could not close the pop-up either, or even just press the back button on the left side of the pop-up.

It has not happened to me before so I am not sure if it is reproduce-able, but to the best of my knowledge what I did was this.

1. Go into queue for a normal game on Summoners Rift.
2. Look at a friend's match history.
3. When a game is found, accept it. That was it as far as I can remember.
